In this paper, we provide matching (up to a constant factor) upper and lower bounds on the degree of polynomials that represent symmetric boolean functions with an error 1/3. Let &Ggr;(f)=min{|2k–n+1|:fk ≠ fk+ 1 and 0 ≤ k ≤ n – 1} where fi is the value of f on inputs with exactly i 1's. We prove that the minimum degree over all the approximating polynomials of f is &THgr;((n(n-&Ggr;(f))).5). We apply the techniques and tools from approximation theory to derive this result. |
